It is very cosy, clean and new apartment. Location is close enough both to the city center and Tegel airport. The host is really hospitable. I'm sure you will enjoy your stay here.
We travel to Berlin at least once a year, and this time we rented this particular apartment because it was out first trip with our daughter who is 6 months old.
The apartment is very nice and very clean, and everything is very new. There is not a bathtub, but there is a large shower. Everything is incredibly stylish. The only downside for us was the soft mattress. Both of us like hard mattresses, and this one is quite soft. However, I think one of my sisters would have enjoyed it.
The kitchen is very well equipped. I can't think of anything that was lacking.
If you're bringing a baby, there is a high chair and a baby bed that our daughter thought were really good. However, as mentioned there is no bathtub and it's on the fourth floor (or third floor, depending where you come from) so it is inconvenient with a stroller. We also rented a parking spot right outside of the building so we kept the stroller in our car. Still, with a car it was really good for a couple with a baby.
The location is in Moabit, which while centralish isn't exactly where the action is (We traveled to different areas every day). As a result, it was quite quiet in the night, and we slept with windows open because it was very hot. The apartment is about 10 minutes by foot to the Turnstrasse U-Bahn station. Along the way are Turkish restaurants, two Turkish grocery stores, and a DM (a drug store, where we bought baby food and toiletries we had forgotten). Not too far away are Indian restaurants, but we only ate one time in the neighbourhood, the rest of the time venturing out to other neighbourhoods.
At the end we left our key in the apartment. That required going back up after opening the car gate, which was not a problem but we would have been embarrassing to have closed the apartment door and have to call Luidmila to come and open up for us. I'm sure she would have been very helpful, as she and her husband seem very nice and quick to respond.
